Using an Aquamog - a machine that works like a Rototiller but can float on water - researchers Pamela McLeod (left), Upal Ghosh and Dennis Smithenry are working with Richard Luthy, a Stanford professor of civil and environmental engineering (not pictured), on an experiment in southeast San Francisco that involves mixing activated carbon into sediment to prevent pollutants such as PCBs from entering the aquatic food chain.
